I've seen some other postings about higher addresses failing, but none about block 0 failing.
This is a "27 menu" model of the uv-b5.
Downloading works fine.

I've tried uploading both modified and completely unmodified images to the radio. All fail with the same "Radio NAK'd block at address 0x0000" error.
A bit more info:
After resetting the uv-b5 via the startup menu (hold menu and power on), I was able to:
- download an image
- partially upload that same image (Ended with "Radio NAK'd block at
address 0x0f00"
After doing this, the radio:
- no longer accepts new images (appears in the same state as it was before)
- displays a lock icon on the display
- doesn't appear to let me get back to the initialization menu
Link to the image downloaded after reset but before reuploading:

And the version read back from the radio after reuploading:
